This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are \"closed\". A reed petal never truly \"closes\" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact, sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer are they receive less wear than the reed petals on a conventional reed valve design.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003e\u003cstrong\u003eSTANDARD VFORCE REED VALVE FEATURES:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eDouble the reed tip surface over a conventional reed valve design\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eIncreased bottom end, stronger mid-range and longer top-end\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eGreater efficiency due to reduced reed petal travel\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eMore airflow means more horsepower\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eReduced reed petal wear\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eScrew free design eliminates risk of screws going through motor\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eScrew free design enables rapid reed petal changes\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003e\u003cstrong\u003eIMPROVED VFORCE4 FEATURES:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eAll-new reed petal resin system, carbon fibre and lay-up\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003ePre-curved reed petal ensures better seal at tip\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eWider reed cage for maximum airflow\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eCombined reed tip area increased by 10.5% resulting in increased total air flow\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eAirfoil shape added to cage tip to increase air velocity from outer ports\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eLong reed stops added to progressively slow petal tip velocity, for increased petal durability\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eReduced frontal area of central wing by 15.6% combined with a more aerodynamic shape\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003e\u003cstrong\u003eALL-NEW VFORCE4R FEATURES:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eRubber overmolding on reed tip surface of cage to further enhance petal life\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan style=\"font-size: small;\"\u003eAll-new manifold, reed cage and air guide designed for the VFVorce4R\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003e\u003cstrong\u003eWHAT'S INCLUDED WHEN I PURCHASE THE VFORCE4R REED VALVE SYSTEM?\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-size: small;\"\u003eMoto Tassinari and VForce4R decals, detailed installation instructions, complete VForce4R reed valve system (including reed petals) and gasket.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e","brand":"V-Force","offers":[{"title":"Default Title","offer_id":53272349901066,"sku":"vforce.800310","price":165.9,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/store.phoenixmotos.com\/products\/v-force-vf4-sx250-07-16-exc250-03-16-exc300-04-16-beta-300rr-13-22","provider":"Phoenix Motos","version":"1.0","type":"link"}
